Language Development
B. F. Skinner: association (of the sights of things with the sounds of words); imitation (of the words and syntax modeled by others); and reinforcement (with smiles and hugs when the child says something right)
Language Development
Noam Chomsky: Given adequate nurture, language will naturally occur.
It just “happens to the child.”
We come prewired with a sort of switch box—a language acquisition device.
